T all 10772 it may concern: 7

Be it known that I, WALTER R. 'Woons. a. citizen of the United States,and av resident of the city of Chicago, county'of Cook, and State ofIllinois, have invented certain new and useful Improvements in UniversalJoints, of whichthe following is a specification.

My invention relates to improvements in universal joints for powershafts of power driven vehicles, such as automobiles, motor cycles, andthe like, and has for its objet the provision of an improvedconstruction of this character arranged and adapted to prevent suddenjars and shocks in thespplication of the power. 7

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereininafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a vertical section of a construe is provided co-aXially on'itsouter side with .inents of'said blocks.

a perforated securing lug 5, to whirh a section of the power shaft. 6 ispivotally con nected by means of a pin 5. Likewise the disk 4!. isprovided with a coaxial projection '7 to which the shaft section 8 ispivotally connected by means of the pin 7', said pins 5 and 7 beingarranged at right angles to each other, as shown, so as to effect auniversal joint connection between the shaft sections 6 and 8. The disk3 is provided with two oppositely disposed scg mental slots 9' adjacentthe periphery thereof, and disk 4 carries twoistops or blocks 10positioned substantially centrally in the 'slots9 and arranged to slideangularly therein. as shown. The blocks 10 are secured in place bymachine screws 11, and com pression springs 12 are imprisoned in eachslot 9 on each side of the corresponding block 10, thus torsionallyresisting the move- Segmental guard plates 13 are also secured to theblocks. 10

on the side of disk 3 opposite to the disk 4t to insure imprisonment ofsprings-12 during their operation; By this arrangement,

it will be observed that, upon application of power to one of the shaftsections, said power. will be transmitted to the other shaft sectionthrough the medium of the springs '12, thus effecting a torsionallyyielding connection between said shafts, which tends to lessen theshocks and jars incident to the application of power, as in automobiles,motor cycles, and'the like, and tending to increase the smoothness withwhich such vehicles may be operated, and also tending to minimize thedanger of stripping the gears of the transmission therein.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect this is capable ofvariation and modification without departing from the pirit of theinvention. I therefore, do not wish to be limited to the precise detailsof the construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. A universal joint for power shafts comprising two universal jointmembers arranged adjacent each other; perforated lugs on the outer sidesof said members, the perforations in said lugs being at substantiallyright angles to each other; shaft sec tions pivotally connected withsaid lugs; and a. torsionally yielding connection be tween said members,substantially as described.

2. A universal oint for power shafts comprising two universal jointmembers arprising two disks arranged facing each other, one of saiddisks being provided with two oppositely arranged segmental slots; stopson the other disk operating in said slots; springs resisting movementsof said stops in said slots; and shaft sections pivally as described.

ot-ally connected With said disks, snbstanti-t 4:. A universal joint forpower shafts of power ClIIV-GH'VBhH'lGS, comprising two dlsks arrangedfacing each other, one of said disks being provided with two oppositelyarvranged segmental slots; stops on the other disk positionedsubstantially centrally' in said slots and arranged to swing circiunferentially therein; compression springs p0- said disks, theperforations in said lugs be- .ingatsubstantially right angles toueach15 other; and shaft, sections pivotally connected with said lugs bymeans of pins extend 7 ing through said perforations, substantiallyasdescrlbedh r In testimony whereof I have signed my 20' name to thisspecification in the presence of two subscribing witnesses.
